This patch is fix for https://sourceware.org/bugzilla/show_bug.cgi?id=19583

As per the suggestion, defining new bit_arch_Prefer_Fast_Copy_Backward and index_arch_Prefer_Fast_Copy_Backward feature bit macros to update IFUNC selection order for memcpy, memcpy_chk, mempcpy, mempcpy_chk, memmove and memmove_chk functions without affecting other targets. PFA patch and ChangeLog files to this mail. If OK please commit it from my side.


Thanks,
Amit.
